Editing string from a JTextBox

Question

hallo.
I'm trying to make a simple text editing program. You input a sentence, and a method changes some words to others:
For example, you put in this sentence: "Patty is not a tool"
And this comes out: "Patty is totally a tool"
The edited sentence will appear in JLabel fixed.
Here's the code:
import javax.swing.*;
import java.awt.event.*;
import java.awt.*;
public class Sentence extends JFrame implements KeyListener {
     JTextField text = new JTextField(10);
     public String text2 = text.getText();
     public String sent1 = "";
     JLabel label = new JLabel("Type a sentence so that I can fix it for you.");
     JLabel fixed = new JLabel("--");
     Sentence() {
          super("Sentence Correcter");
          setSize(350,100);
          setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
          setBackground( Color.black );
          text.addKeyListener(this);
          FlowLayout flo = new FlowLayout();
          setLayout(flo);
          add(label);
          add(text);
          add(fixed);
          setVisible(true);
     public void keyTyped(KeyEvent in) {
          fixSentence(text2);
          System.out.println(""+text2);
     public void keyPressed(KeyEvent na) {
     public void keyReleased(KeyEvent na) {
     public void fixSentence(String sent) {
          fixed.setText(""+sent);
          String a = "a";
          String b = "b";
          sent.replaceAll(a, b);
          fixed.setText(""+sent);
          System.out.println(""+sent);
     public static void main(String[] args) {
          Sentence s = new Sentence();
}that changes all "a" to "b". Doesn't work of course. What am i missing?

Sorry, i'm not sure if bumping is aloud, but my problem still exists. Here's what I have now for code:
import javax.swing.*;
import java.awt.event.*;
import java.awt.*;
public class Sentence extends JFrame implements KeyListener {
     JTextField text = new JTextField(10);
     public String text2 = "";
     public String[] realWords = {"the", "and"};
     public String[] newWords = {"teh", "adn"};
     JLabel label = new JLabel("Type a sentence so that I can fix it for you.");
     JLabel fixed = new JLabel("");
     Sentence() {
          super("Sentence Correcter");
          setSize(350,100);
          setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
          text.addKeyListener(this);
          FlowLayout flo = new FlowLayout();
          setLayout(flo);
          add(label);
          add(text);
          add(fixed);
          setVisible(true);
     public void keyTyped(KeyEvent in) {          
     public void keyPressed(KeyEvent in) {
          int key = in.getKeyCode();
        if (key == KeyEvent.VK_ENTER) {
               text2 = text.getText();
               fixSentence(text2);
     public void keyReleased(KeyEvent na) {
     public void fixSentence(String sent) {
          for(int i = 0; i < realWords.length; i++) {
               sent.replaceAll(realWords, newWords[i]);
               sent.trim();
               fixed.setText(sent);
     public static void main(String[] args) {
          Sentence s = new Sentence();
} Now it outputs exactly what i type in the JTextBox, after I hit the ENTER key. It still doesn't replace the realWords with newWords, and I can't figure out why.
